Friendly warning! We're working hard to be accurate. But these are unusual times, so please check that venues remain open.
There are two escape games on offer here: 'trapped in a prison van' and 'trapped in a room with a zombie', which we think looks like the best one. It features a 'real' zombie – as in not a mannequin or automaton like other games – and is for groups of ten (smaller groups will be placed together, so don't be shy). You all have an hour to find clues and solve riddles to get the hidden key and avoid a grizzly end, all the while the zombie will be gaining as every five minutes the its chain will slacken.
Note that this game is only open Wednesday to Sunday, but you can hire a third game – 'trapped undercover' – to take place at a location of your choice at any time.
